wrong the iq is no different,
Perhaps you would like to explain further the basis of that statement?

Are you saying that Sigma are telling porkies when they say:

DG (Digital) Lenses:
The most suitable lenses for 35 mm film single-lens reflex cameras, as well as for digital SLR cameras. Sigma’s development of the DG (Digital) range of lenses has concentrated on the correction of distortion and aberrations. Magnification of chromatic aberration is particularly conspicuous with digital cameras. The optical designs and cutting-edge technology incorporated by Sigma eliminate flare and ghosting from the image sensor and create excellent color balance. Vignetting is minimized whilst marginal illumination is ensured. These high performance lenses are equally suited for digital and analogue cameras.

==================================

Possibly not too reliable but http://www.dyxum.com gave slightly higher marks to the DG version for sharpness.

We also have to bear in mind that Sigma lenses do tend to vary quite a bit even with supposedly identical lenses.

Just for my curiosity, how much did you get through ebay?
Just search through completed items.
Could they be the one's that went for £600 and £525?
Both same seller from the right part of country.

I wouldn't say there was anything wrong with that?
Two ducks with flat lighting, probably better than
contrasty side lighting. At least the Daylight looks
to be of a good colour temperature.

You should see some of my saved ebay searches, here's one from when I was keeping an eye out for a Pentax 300mm:

Pentax, (300, 300mm) -70 -80 -60 -55 -100 -75 -28 -70mm -80mm -60mm -55mm -100mm -75mm -28mm -af70 -af28 -6x7 -67 -600 -1000 -900
That's a good one Tim

MXV were doing things like:

Pentax {55 mm - 300 mm} f 4-5 - f 5-8

they couldn't even do that consistently

How many people on here actually searched for a lens and found MXV came up in the results?

If I'm in the market for a Sigma 150-500mm I search on ebay for "Sigma Pentax (500, 500mm) -(flash, diffuser)"
That works, but if you leave out "Pentax" it hits 115 items.
There's no substitute for seller copying the description accurately off the manufacturers box. It shouldn't be down to the buyer.

The advantage of 500mm in the description in the photography section is that nearly all the results will be for a lens.

One grey area is with apertures. Because f/8 technically is the diam. of the aperture, it shouldn't be abbreviated to f8 or f5.6, but manufacturers do that so I suppose it has to be accepted. Some even use f:8

500 and 500mm are two completely different words . Every lens manufacturer in the world uses 500mm as the lens description

If I'm in the market for a Sigma 150-500mm and type that into ebays search box it picks up 15 lenses, but not the SRS one, which is OK if they aren't interested in selling it, and a lot of people who list on ebay aren't

Now you've learn't something about listing and searching for lenses on ebay

Sigma 500 is also a flashgun (EF-500)

I thought SRS were one of the more intelligent dealers
but after seeing them advertise a 500mm lens on ebay as 500
I'm not to sure

Anyway I'll do them a favour and list it here:

SIGMA 150-500 F5.6-6.3 HSM - PENTAX - NEW - UK DEALER!

£649 BIN 2 available

I'd also say if it was a DG or not if it was me selling it, but
I'm not and I'm not doing anymore work for SRS

I once wrote to MXV telling them that every lens they had listed
on ebay wasn't listed correctly and that it wouldn't be caught by peoples searches resulting in them missing a lot of sales. I got a nasty email back saying that they had been selling lenses for xx years and knew
best how to sell them. They carried on with their own way of listing. About 2 months later they went bust
